Side by side
Scorafy vs CoGrader
CoGrader is a classroom teacher's tool: state rubrics, Google Classroom, a generous free tier, and fast first-pass grading of essays. Scorafy is built for assessments where the judgement has to be defended afterwards - RTO competency sign-offs, university coursework, workplace certification - so every criterion score cites evidence from the submission, results wait behind a release gate, and every override is kept in an Audit Pack.
AI-powered assessment platform that analyses each respondent's specific answers and generates a unique, personalised report with personalised strengths, development areas, and recommendations.
Free plan available. Self-serve paid plans from $39 USD/month (Starter) to $249/month (Pro), with Business and Enterprise plans quoted. Education and non-profit organisations get 40% off Starter, Growth and Pro. Per-respondent AI assessment is included on every paid plan.
CoGrader is an AI essay grader built for US K-12 teachers. A teacher imports a class set from Google Classroom or by file, picks one of 500+ state-aligned rubrics or writes their own, and CoGrader drafts a grade and feedback for every student. The teacher reviews and adjusts both before anything is finalised. Handwritten work can be uploaded as photos or PDFs on paid tiers, and the free tier covers 100 submissions a month.
Free Starter plan (100 student submissions a month, Google Classroom, FERPA). Standard $15 USD/month billed annually or $19 monthly for 350 submissions and handwritten uploads. Schools & Districts and Higher Ed & Enterprise on quote, with Canvas and Schoology at that level. Checked 11 Sep 2026 - see cograder.com/pricing for current figures.

Where each platform excels
An honest look at what each platform does best.
CoGrader strengths
- Purpose-built for US K-12: 500+ state-aligned rubrics remove the rubric-writing step entirely
- Google Classroom on every tier, Canvas and Schoology for schools and districts
- Handwritten essays and worksheets accepted as photos or PDFs
- Plagiarism and AI-writing detection alongside the grade
- The free tier (100 submissions a month) covers a realistic single-teacher load
- Cheaper entry price for an individual teacher than any Scorafy paid plan
- Every criterion score cites the passage of the submission that earned it, so a reviewer can check the AI in seconds rather than re-read the answer
- Release gate: nothing reaches the respondent until a qualified assessor signs off
- Overrides keep both the AI score and the human decision, with identity and timestamp, exported as an Audit Pack
- AI-marks audio, video and file submissions as well as typed answers
- Delivers the assessment itself: branded respondent links, cohort analytics, and per-respondent reports
- EU data residency in Dublin with an optional Sydney region, and submissions are never used to train models
Why choose Scorafy?
The fundamental difference is in how responses are analysed. Most platforms - including CoGrader - treat responses as data points for aggregate reporting or template-based result pages.
Scorafy reads each respondent's specific answers - including free-text responses - and generates a completely unique assessment report. Every person gets personalised strengths, development areas, and actionable recommendations written specifically for them.

Our honest recommendation
CoGrader is the right choice for a classroom teacher grading essays against state standards - the pre-built rubrics, Google Classroom link, handwriting support and free tier are built for that job, and Scorafy has none of them. Choose Scorafy when the mark has to hold up outside the classroom: RTO and VET competency evidence, university coursework under academic-integrity scrutiny, professional certification, or workplace capability assessments. There, per-criterion evidence, a release gate and an Audit Pack are the product, not extras.
